v1.12.2

Compare Source

===================
This release fixes a cargo doc breakage on nightly when --cfg docsrs is
enabled. This caused documentation to fail to build on docs.rs.

Bug fixes:

• BUG #​1305:
  Switches the doc_auto_cfg feature to doc_cfg on nightly for docs.rs builds.

v1.12.1

Compare Source

===================
This release makes a bug fix in the new regex::Captures::get_match API
introduced in 1.12.0. There was an oversight with the lifetime parameter
for the Match returned. This is technically a breaking change, but given
that it was caught almost immediately and I've yanked the 1.12.0 release,
I think this is fine.

v1.12.0

Compare Source

===================
This release contains a smattering of bug fixes, a fix for excessive memory
consumption in some cases and a new regex::Captures::get_match API.

Improvements:

• FEATURE #​1146:
  Add Capture::get_match for returning the overall match without unwrap().

Bug fixes:

• BUG #​1083:
  Fixes a panic in the lazy DFA (can only occur for especially large regexes).
• BUG #​1116:
  Fixes a memory usage regression for large regexes (introduced in regex 1.9).
• BUG #​1195:
  Fix universal start states in sparse DFA.
• BUG #​1295:
  Fixes a panic when deserializing a corrupted dense DFA.
• BUG 8f5d9479:
  Make regex_automata::meta::Regex::find consistently return None when
  WhichCaptures::None is used.

v1.11.3

Compare Source

===================
This is a small patch release with an improvement in memory usage in some
cases.

Improvements:

• BUG #​1297:
  Improve memory usage by trimming excess memory capacity in some spots.

v1.11.2

Compare Source

===================
This is a new patch release of regex with some minor fixes. A larger number
of typo or lint fix patches were merged. Also, we now finally recommend using
std::sync::LazyLock.

Improvements:

• BUG #​1217:
  Switch recommendation from once_cell to std::sync::LazyLock.
• BUG #​1225:
  Add DFA::set_prefilter to regex-automata.

Bug fixes:

• BUG #​1165:
  Remove std dependency from perf-literal-multisubstring crate feature.
• BUG #​1165:
  Clarify the meaning of (?R)$ in the documentation.
• BUG #​1281:
  Remove fuzz/ and record/ directories from published crate on crates.io.

v0.8.9

Compare Source

Fixed

• Allow the unstable-provider-api feature to be used in a no_std
  environment, both with and without the alloc feature flag enabled.

v0.8.8

Compare Source

Fixed

• Gate TryFuture::whatever_context,
  TryFuture::with_whatever_context, TryStream::whatever_context,
  and TryStream::with_whatever_context behind the alloc feature
  flag. This allows SNAFU's future and stream combinators to be used
  in a no_std environment.

• Only implement GenerateImplicitData and AsBacktrace for Arc
  wrappers when the target platform has access to atomics and Arc.

v0.8.7

Compare Source

Added

• GenerateImplicitData and AsBacktrace are now implemented for
  Box<T>, Rc<T>, and Arc<T> when T implements the same
  trait. This allows you to use types like Arc<Backtrace> as a
  backtrace field.

v3.23.0
